Dissertation help, wind turbine output

Click For Summary

Discussion Overview

The discussion revolves around the power output of a wind turbine when it is in motion, specifically when attached to a bicycle, and the implications of wind speed in this scenario. Participants explore the relationship between the turbine's movement and the perceived wind speed affecting its output, considering various factors such as swept area, air density, and efficiency.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions how the wind turbine perceives its movement relative to the wind.
  • Another participant suggests that if the turbine is moving at 10mph, it effectively creates a 10mph wind in the opposite direction.
  • A later reply confirms the idea that the movement of the turbine generates a relative wind speed.

Areas of Agreement / Disagreement

Participants appear to agree on the concept that the turbine's movement creates a relative wind speed, but the implications for power output remain under discussion without a clear consensus.

Contextual Notes

Participants have not fully resolved how to calculate the power output under these conditions, and assumptions regarding the relationship between wind speed and turbine output are not explicitly stated.

This is a question that i am struggling to find any answer to on the internet.

Doing some research for my 4th year honours dissertation.

I have a wind turbine capable of producing a certain output at say windspeed of 10mph.

Meaning that the wind is moving towards the turbine at 10mph.

What is the situation if the wind turbine is actually traveling (attached to a bicycle) at 10mph and say in this case the windspeed is 0.

How can i now work out the power output assuming i know all the other variables like the swept area, air density, efficiency etc

Thanks in advance for any input!

first time doing this, iv clearly done the post wrong somehow, still appreciate any thoughts
 
How does the wind turbine know if it is moving or stationary w/respect to the wind?
 
it dosent, what I am wondering is if the device is moving at 10mph does that create 10mph winds in the opposite direction?

Yep.
 
awesome, thanks for clarifying
